Following Friday, 19th September up: For one of the "two very very important things" they wrote back, asking for yet more documentation!

It's part of a cunning scheme to keep Australia Post (formerly known as the Postmaster General's Department before they split it into separate mail & telephone parts) going.

It's part of a scheme to keep the (semi-government??) body they're in looking busy so they don't get "rightsized" into the unemployment pool - cold, dirty & carnivore-infested bog that it is.
